Printrbot files in the wild!

Thought you would all like to know the official Printrbot files have been published on thingiverse! They were getting downloads even before I finished publishing everything. It will be fun to see how quickly someone will build one and get one printing. I'll send a free set of Printrbot LC parts to the first verified printing Printrbot. Happy printing, Brook

      One more thing, it this printer ends up printing exactly the same lousy parts, we've been taken. In that case, lesson learned.

      The tolerance of these pieces are shit. Maybe great if you have full outfitted machine shop you might stand a chance of actually getting this thing together, else your f_cked. I just ruined two linear bearings and wish me luck finding new ones. Missing holes, instructions that force you start over because parts have changed, missing details, 2 hours my ass! my worst kickstarter project to date.

      My kit arrived today. Still looking for instructions........?

      You got my money months ago and have heard anything about a shipping date or any communication. Just send me an email so I know that I am on the list

      Yes, also wondering about delivery being on track? Thank you !

      Hi. Is delivery still on track for this month?

      Personally I'd prefer an ATX supply for the simply fact that it'd be very easy for me to replace, and it should have a number of extra connectors available for things like adding a fan here and there. It would also make it easier to expand to a larger print bed since it will consume more current to heat and it's easier to get a larger supply to do that.

      Same here ATX ones are ridiculously huge :/

      I would like to hear about the power supply, too. Any decisions? I'm hoping that there will be additional 12v connectors available on it for a fan to help exhaust plastic fumes.

      Not sure if you've figured out the power supply issue but "" the maker of gaming mice just came out with a new laptop the BLADE that uses a new power supply . Might be something to look into looks like they've sourced it themselves so its not an old design , looks to be way smaller than the xbox brick .
      their number is US (Toll-Free) International
      1-855-87-BLADE (25233)
      might be just whats needed

      You mean... like RepRap printers of varying design and quality just keep popping up?
      Oh, wait, that was the whole point ;)

    12. Russell Nelson on February 6, 2012

      Brook, you should take some steps to protect your trademark Printrbot. It's not hard. You have to have a generic name for devices manufactured to the same design as your Printrbots. Maybe call it the "Edison Reprap" or something like that. But if somebody calls a 3D printer "Printrbot", it had better be one that you put your hands on. Otherwise people "Printrbot" will become the generic name for all printers made to your design, whether you touched them or not. And when people tlak about a "printrbot", nobody will know if it came from you or not. Maybe you don't care. If you don't, then expect "Printrbots" of varying quality to show up. Some of them won't work at all, and without a trademark, nobody will be able to tell if it's your product or somebody else's.

      Come on, folks, read. Carefully. Everything's stated clearly in black on white.

      "we will upgrade our printrbots to an 8x8"model"
      OUR printrbots. Not your printrbot. Meaning the printrbots that are used at the bot farm, to increase manufacture capacity.

      Also, what the heck is unclear about the model lineup? It's all clearly described in the sidebar, for crying out loud. Not to mention it's been described clearly enough in the updates.

      - Printrbot = plastic parts, expandability, 6"x6"
      - Printrbot LC = laser cut MDF, less easily expanded, 6"x6"
      - Printrbot+ = laser cut MDF, less easily expanded, 8"x8"

      All of these are expandable, it's just that for the latter two you'll need to print more extra parts in order to expand them, since you'll need to replace all the wooden parts.

    14. Ryan Voots on February 5, 2012

      My understanding is that the Printrbot and Printrbot LC both come with a printbed of 6"x6". the Printrbot+ is one built to handle an 8"x8" printbed from the start. What happened in those updates was that they found that they could fit an 8"x8" print bed on the standard printrbots (regular and LC) without making the frame any larger. My suspicion is that even with an 8"x8" the original printrbots won't print all the way to the edge on them (e.g. you'd get max something like 7"x7" actual printable area). The printrbot+ should also be able to be expanded in a similar manner to get an extra inch or two.

      If the normal bot is going to be 8x8 then what's the point of the printrbot+? Does it get an upgrade also?

      Hi Brook,
      I have a few quesions about the recent upgrade offer you made on update #17. You are offering an upgrade to the printrbot+ for $150. But I am confused whether the printrbot+ is just a larger printrbot or is the laser cut printrbot (because you call this one the printerbot LC) So the first question is: is the printrbot + the same as the printrbot LC?

      Also, on update #14 you said (I highlighted in red):

      Update #14: Strong Finish: $830,827
      Posted on December 19
      BOT FARM UPDATE: We are slowly working on the bot farm. We will be moving into a location in Lincoln (out of my garage). Alex is preparing the bots for the farm as I type. We will be using printrbot+ models as well as (plastic) printrbots. We discovered the regular printrbots do barely accept an 8.25 x 8.25 heated bed, so we will upgrade our printrbots to an 8x8"model with longer smooth and threaded rods. Our upgrade will not include the z-height, since it will be unecessary - I actually have a bunch of 9" rods I need to use anyway. We will show video of the printrbots at the botfarm, but no promise on how soon.

      So, second question is: are the regular rpintrbot NOT coming with an 8 x 8´ bed now ?

      In my case, I would like to upgrade the size, but I am not so fond of the LC concept becasue it can not be upgraded further. So I pledged for a regular printrbot and plan to make it larger, either with an upgrade of yours or by myself

      Thanks for a great job and look forward to your response

      I am a fan of sketchup and most certainly would appreciate a copy of the printrbot virtual kit you are working on.

      How about taking the two minutes or less it would require to answer my emails telling you I would prefer the laser cut printrbot when you ship me my machine. This is at least the fourth time I have attempted to contact you.

      @Arvin: If you happen to assemble one completely in Sketchup, could you publish the file? I'dd like to print a small one on the UP in one go as deco or keychain thing :-)

    20. Arvin on February 4, 2012

      The pb-x-Motor.skp file was really an stl. I loaded all of the skp files in sketchup. Found a few faces reversed and a few lines that were extra. I'm putting the pieces together now to see what goes where.

      Can't put my kit together so, hey, I'll put together a virtual kit!

    21. Marcus on February 4, 2012

      Okey, they are not usable, but hey, it's the first batch out in the wild ;-)
      I think I will make a fakebot out of them and put it on my desk.

    22. Marcus on February 4, 2012

      I'll check if I have enough ABS, hehe. Just set up my printer again at home.
